Question

2. State whether this change can be reversed or not.

(d) Baking cake in an oven.

Answer 1

• A change that can be reversed or can get back to its original state is called a reversible change.
• During baking a cake, the ingredients of cake mix up and baked.
• The baked ingredients of cake cannot be separated and extracted back to their original state.
• Hence, this is an irreversible change and cannot be reversed.
